Are you Mark or Shelle's daughter?They are my cousins, but I was quite small the last time I saw either of them.
Jim (your grandpa) is my Uncle.His brother Ken was my Dad.I actually live in Michigan now, but I grew up in Spicer, Mn.
I have some family tree information that my Grandma Esther (Jim's Mom) sent me about 15 years ago.It traces the family back to George Kerfoot who was an Englishman living in Ireland who emigrated to Canada, before moving South to the enjoy the balmy Minnesota weather.
Send me an e-mail and I'll be happy to share what I have with you. (I might have to do a little searching)
